POTTERY-MACHINE.

SPECIFICATION forming part of Letters Patent No. 468,391, dated February 9, 189.2.

Application tiled February 25, 1891. Serial N0. 382,712. (No model.)

To @ZZ whom t 11mg/ concern.-

Be it known that I, WILLIAM J. VOOLLEY, a citizen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Pottery or Retort Machines, of which the following is a specification, reference being had therein to the accompanyin g drawings.

This invention relates to certain new and useful improvements in retort or pottery machines and is designed for forming bottoms on retorts, pipes, and other articles.

It has for its objects, among others, to provide a disk which forms the bottom of a material that will prevent sticking of the clay thereto. l have found that satisfactory results cannot be obtained by the use of an iron plate or disk. Experiments with such have resulted in the sticking of the clay thereto and a consequent Waste of the material and loss of time. l iind that a wooden disk or plate is the most satisfactory. lt may be, perhaps, the only material which will work perfectly satisfactorily. I provide means for holding the clay While the bottom is being formed, and thenremoving the same from the mold, forming the sides as the material is removed, and, when it has reached the desired length, cut it off and raise the support ready for another operation." The support or bottom of the mold is carried by a counterbalance device, which renders it easy of manipulation. The said bottom is provided with lugs or projections, which, when the said bottom is rotated, slightly serve to disengage the latches Which hold the bottom in place.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specically defined by the appended claims.

The invention is clearly illustrated in the accompanying draWings,Which, with the letters of reference marked thereon, form a part of this specification, and .in which- Figure l is a side elevation of myimproved machine with parts in section. Fig. 2 is a central vertical section through the die or mold and bottom-former y on an enlarged scale. Fig. 3 is an end view of the counter-balance for the moldbottom. Fig. l is abottom plan of the said bottom and its operating-handle on an enlarged scale.

Like letters of reference indicatelike parts throughout the several views.

Referring now to the details of the drawings by letter7 A designates the frame-Work, which may be of any form suited to the purpose, and Bis the main shaft, journaled in suitable bearings or boxes a on the frame and carryingthe drive-pulley A', driven from any suitable source of power. (Not shown.) On this shaft is a bevel gear-Wheel B', fast thereon and arranged to Work in a depression b, provided in the frame therefor, as seen in Fig. l. This bevel-gear meshes Withalarger gear- Wheel C, carried by a vertical shaft C', suitably journaled in bearings or boxes in the frame and at its upper end carrying a gearwheel D, Which meshes with a larger gear- Wheel D on the vertical shaft E, which is suitably journaled in the frame and carries at its lower end the bottom-former, as seen in Fig. l. This bottom-former consists of the head F, through which the shaft or core passes, and is secured thereto, as seen in Figs. l and 2, the end of the shaft being reduced and screw-threaded and provided with retaining nut or nuts c, as seen in said Figs. l and 2. This head is internally threaded, as at d, and G is the bottom disk or plate, which is formed of Wood and provided With anV upwardly-extending externally-threaded fiange e, which engages the threads of the head, as seen best in Fig. 2, being centrally chambercd, as seen at f, to provide room for the retaining-nuts. The Wooden bottom disk'or plate Will not stick to and retain the clay. This is most essential for good Work in this class of machines. Being detachable, it can be readily removed when necessary.

Depending from the frame is the hopperor clay-chamber Il, which is flanged, as shown in Fig. l, and to the lower flanges is secured the die or mold I, which is tapered for a portion of its height and at the lower end provided with substantially vertical Walls. lVithin this die or mold the bottom-former Works, as seen in Figs. l and 2. J are latches secured to the side Walls of this vertical portion of the die or mold, and K is the bottom of the IOO die, which is provided with diametrically-opposite lugs or projections g, designed to engage the said latches, and thus be held in place While the bottom of the Vessel is being .plate is carried by a Vertical rod or support L,

which is guided in a suitable guide on the floor L', as seen in Fig. l. At its lower end it is secured to a cross-bar M, tothe ends of which 'are connected the cords or chains N, which Y raise or lower the cross-bar, and consequently the bottom plate. The vertical shaft preferably extends through a suitable stand or casing, as seen in Fig. l.

Any suitable means, as the spiral conveyei S, may be employed to feed the clay downward.

What I claim as new is- 1. The combination, with the die and the detachable bottom plate thereof, of the rod carrying said plate, the cross-bar attached to said rod, the shaft and pulleys, the handwheel and intermediate mechanism for revolving saidY shaft, the chains connected to the cross-har and passed over said pulleys, and the Weight attached to the other ends of said chains, substantially as specified. 'e

2. In a machine of the class described, the combination of the core or shaft E, the chambered head through which the shaft passes, the chambered bottom plate detachably engaged With said head, and the nut upon the end of the shaft Within the said chamber and serving to hold the head upon the shaft, substantially as described.

In testimony whereof I affix mysignature in presence ef two Witnesses.
